The study was conducted to determine the effect of concentration, frequency, and temperature of the black tea solution to discoloration of tooth enamel. 17 teeth divided into the positive control group, negative control, a concentration of 1%, 2% and 3%, frequency 60 and 180 times, and the temperature of 30°, 37° and 45°. The color change was analyzed by photometer and CMY. There is discoloration of the enamel becomes darker (r²=0.472; p < 0.05). Increased concentration, frequency, and temperature of the tea followed by an increase in dark colors on the enamel.
